Fifty-euro notes are seen at the Belgian Central Bank in Brussels December 8, 2011. European Union leaders will discuss proposals for tighter euro zone integration on December 8-9, with the aim of bringing deficits and debt much more strictly into check, a move that may give the European Central Bank room to step up purchases of sovereign bonds and reassure financial markets.
